Those are grouped into 4 steps: system startup, bootloader stage, kernel stage, and init process. [3] When a Linux system is powered up or reset, its processor will execute a specific firmware/program for system initialization, such as the power-on self-test, invoking the reset vector to start a program at a known address in flash/ROM (in ...
Research Unix init runs the initialization shell script located at /etc/rc, [2] then launches getty on terminals under the control of /etc/ttys. [3] There are no runlevels; the /etc/rc file determines what programs are run by init. The advantage of this system is that it is simple and easy to edit manually.
In Linux systems, initrd (initial ramdisk) is a scheme for loading a temporary root file system into memory, to be used as part of the Linux startup process. initrd and initramfs (from INITial RAM File System) refer to two different methods of achieving this.
After the Linux kernel has booted, the /sbin/init program reads the /etc/inittab file to determine the behavior for each runlevel. Unless the user specifies another value as a kernel boot parameter , the system will attempt to enter (start) the default runlevel.
An INI file is a configuration file for computer software that consists of plain text with a structure and syntax comprising key–value pairs organized in sections. [1] The name of these configuration files comes from the filename extension INI, short for initialization, used in the MS-DOS operating system which popularized this method of software configuration.
systemd is a software suite that provides an array of system components for Linux [7] operating systems. The main aim is to unify service configuration and behavior across Linux distributions. [8] Its primary component is a "system and service manager" — an init system used to bootstrap user space and manage user processes.

The Boot File System (named BFS on Linux, but BFS also refers to the Be File System) was used on UnixWare to store files necessary to its boot process. [ 1 ] It does not support directories, and only allows contiguous allocation for files, to make it simpler to be used by the boot loader.
